the subsystem model name. A different name can be assigned for the subsystem or specific logical drives. This enables ease of identification in a topology consisting of numerous arrays.

1.2.2Drive Trays

Figure 1-8: Drive Tray

The subsystems’ twenty-four (24) drive trays accommodate separately purchased, standard 1-inch pitch, 3.5-inch disk drives. The drive bays are accessed through the front of the enclosure. Two (2) LEDs on each tray bezel indicate the disk drive’s operation status. A rotary bezel lock on each drive tray secures the hard drive in place, while a release button can be used to open the front bezel.

WARNING!

Be careful not to warp, twist, or contort the drive tray in any way (e.g., by dropping it or resting heavy objects on it). The drive tray has been customized to fit into the drive bays in the subsystem and if it is deformed or altered it may not fit into the drive bay.

NOTE:

The redundant-controller subsystem is shipped with twenty-four drive trays with multiplexer (MUX) adapter boards. These MUX boards provide access routes for different RAID controllers.

Please DO NOT use drive trays from a previous Galaxy model, GHDX-7376R6- 24F2D. They are not compatible.

1.2.3RAID Controller Module

The RAID controller module contains a main circuit board and a daughter card providing additional interface connectors, management and host interfaces, and a preinstalled 512MB DDR RAM DIMM. The subsystem comes standard with BBU protection. The BBU is installed in the module bay located at the top center of the controller module. The BBU can be independently inserted or removed.
